Stratigraphic Thickness QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Estimates the stratigraphic thickness of a sedimentary succession, with optional topographic correction using a DEM.
About
This plugin estimates the stratigraphic thickness (ST) of a succession using the classic field-geology traverse method, with an optional topographic correction: ST = d*sin(dip) + Δh*cos(dip), where d is the horizontal distance between the base and the top of the succession, Δh is their elevation difference, and dip is the dip of the strata. Elevation can be read from a DEM layer, entered manually, or skipped entirely for a quick flat-terrain estimate. Successive segments can be chained along a single traverse, each with its own dip, useful for successions with changes in dip. A dedicated (sub)horizontal mode handles beds with dip ≤5° directly from the elevation difference. Any segment can be corrected afterwards by double-clicking it in the list, and the last clicked point can be undone with Backspace. This is an approximation: it assumes a continuous, undeformed succession, measured roughly perpendicular to the strike of the strata. Measuring across an entire folded or faulted succession gives meaningless results, but it works fine within a single fault-bounded block, or on the limb of a fold, as long as the strata keep a fairly constant strike and dip within that segment.
